Androidでメモリ(RAM)情報を取得
Javaコード：
public void getTotalMemory() {
String str1 = “/proc/meminfo";
String str2="";
try {
FileReader fr = new FileReader(str1);
BufferedReader localBufferedReader = new BufferedReader(fr, 8192);
while ((str2 = localBufferedReader.readLine()) != null) {
Log.i(TAG, “—" + str2);
}
} catch (IOException e) {
}
}
